T0 ALL WHOM IT MAY. GONCERN:

ABe it known that I, F. R. FERRIS, of Dora, in the county of Wabash, and in the State of Indiana, have invented certain new'and useful Improvements inTurbine Water-Wheel; and do hereby declare that the fellowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

In the annexed drawings making part of this specification, A represents a. water-Wheel case for a. turbine or horizontal wheel, which is made about twice as deep as the wheel itselt'. Secured in the upper half ot this ease is a rim-wheel, B, which has within it, and extending alittle above it, a hub,'. The rim-Wheel B is made sufficiently smaller than the case A, (less in dialneter,) than the space between the two will be equal to the width ot' the buckets of the wheel. A series of inclined spiral chutes-is secured between the rim B and the case, for the purpose of conducting the water down to the buckets of the wheel. The number of these chutes corresponds with the number of buckets in the wheel, and their mouths are closed by means of a series of gates, L L, which is secured between the two rims D and D. The outer rim, D, rests upon the upper edge-ot` the euse, and the inner one, VD', rests upon the upper edge of the rim B. The gates L are connected by a. series of arms, G G, to a collar, E, which surrounds the wheel-shaft J.. Teeth are formed upon one portion of the periphery of rim D, into which a suitable gear-wheel may mesh to move said rim, and with it theJ gates. Surrounding the upper end oi' hub C is a clutch-collar, H, and the collar E rests upon it. By partially revolving the collar H the gates are slightly raised, so that they can be. easily opened or closed. I represents the wheel, which is provided with a series of inclined spiral buckets, P P, and the verticalshaft-J. The shaftJ passes up through the collar E and hub C. The chutes in the cuse conduct the water to the buckets P P, said buckets receiving not only the direct percussive-stroke of the water, but 'alsothe bach-action from the weight of` the water. The shaft J has its lower bearing in a. suitable step, und its upper bearing in the hub J.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The collar H, in combination with the collar E, arms Gand gates L L, the same being used substantially as and for the purpose set forth. V

In testimony that I claim the foregoing, I have hereunto set my hand, this 23d day of November, 1867.

F. R. FERRIS.
